Enoxaparin is a low molecular weight heparin that is frequently used for the prevention and treatment of deep vein thrombosis (DVT). It works by inhibiting factors in the clotting cascade, particularly factor Xa and, to a lesser extent, factor IIa (thrombin). This anticoagulant is preferred for DVT prophylaxis, especially in situations where patients may be immobile, such as after surgery or during long periods of bed rest.

The key advantages of enoxaparin for DVT prophylaxis include its ease of administration via subcutaneous injection, predictable pharmacokinetics, and the requirement for minimal monitoring compared to other anticoagulants like warfarin. Additionally, enoxaparin provides quick anticoagulation, which is vital in preventing clot formation when patients are at high risk for DVT.

Other options, such as warfarin and rivaroxaban, serve different roles in anticoagulation therapy. While warfarin is often used for long-term anticoagulation once a patient is already established on treatment, it requires regular INR monitoring and dietary considerations. Rivaroxaban, though effective for DVT treatment, is not typically the first choice for prophylaxis due to its specific indications and
